22q11.2 DS syndrome as a genetic subtype of schizophrenia

Introduction The 22q11.2 deletion syndrome (22q11.2 DS) is associated with the microdeletion of this chromosomal region, and represents the second most common genetic syndrome after Down's syndrome. In patients with schizophrenia, 22q11.2 DS has a prevalence of 2%, and in selected groups can be...
